On an airplane's takeoff, the combined action of the air around the engines and wings of an airplane exerts a 8420-n force on the plane, directed upward at an angle of 69.0° above the horizontal. the plane rises with constant velocity in the vertical direction while continuing to accelerate in the horizontal direction. (a) what is the weight of the plane? n (b) what is its horizontal acceleration?

Ineed this now one scientist feels that the changes in global climatic patterns may be good for the health of the biosphere. another scientist feels that sharp changes in climatic patterns could result in the extinction of the biosphere. which of these is the most likely reason the two scientists gave conflicting opinions on the impact of changes in the global climatic pattern? they do not have enough knowledge on the topic. they did not discuss the issue among themselves. they believe conflicting opinion strengthens science. they study different areas of science and have different scientific focuses.
